Answer this with explanation. ​

Answer 1

Answer:

firstly find x

sum of supplementry angles

150 + x = 180

x = 30

x=y [alternative interior angles]

y = 30

70 + B = 180

B = 110

Y + A = B alternative angles

A = 110 - 30

A = 80

Z = B alternatve angles

Z = 110

Answer 2

Answer:

Step-by-step explanation:

b+70=180

so b=18-70=110

Now 150=a+b

150=a+110

a=150-110=40

a+b+x=180

110+40+x=180

x=180-150=30

x= y ( alternate angles )

so y=30

z=b ( alternate angles )

so z=110
